Recurring slope lineae (RSL) in Newton Crater, Mars

Recurring slope lineae are narrow (0.5-5 m wide), relatively dark-toned features that form on steep (25-40˚), southern-hemisphere slopes, and that appear in early spring, grow longer in the downslope direction during spring and summer, and fade during autumn and winter.

Original HiRISE image

Color data has been overlaid on higher-resolution red-channel data. The red-channel data was sharpened first.
